Airbag

Abstract

An air bag formed from a one piece woven air bag material having warp threads ( 10 ) and weft threads ( 20 ) composed of different polymeric fibers. The air bag in accordance with this invention is inexpensive to fabricate without compromises on strength by providing the weft threads ( 20 ) and the warp threads ( 10 ) have the same thread linear density.

The invention claimed is: 
     
       1. An air bag formed from a woven airbag material which consists of polyamide warp threads and polyester weft threads, the warp threads and the weft threads having the same thread linear density, and the airbag material forms a one piece woven airbag. 
     
     
       2. An air bag according to  claim 1 , further comprising that the weft threads ( 20 ) consists of polyethylene. 
     
     
       3. An air bag according to  claim 1 , wherein the warp and the weft threads ( 10 ,  20 ) have a thread linear density between 235 dtex and 700 dtex. 
     
     
       4. An air bag according to  claim 1 , further comprising that the warp threads ( 10 ) consist of nylon. 
     
     
       5. An air bag according to  claim 1 , further comprising that a coating is provided on the warp and the weft threads of the air bag material. 
     
     
       6. An air bag according to  claim 5 , further comprising that the coating consists of at least one of silicone, a coating based on silicone, and an organic material. 
     
     
       7. An air bag according to  claim 6 , further comprising that the coating is a film of a composite material.
